Turboexpander-Dynamometer/Oil Brake

A turboexpander-dynamometer, also known as an expander-dyno/oil brake, is a high-speed machine composed of an expander stage loaded by an oil brake, instead of a compressor or generator. The power generated by the expander is dissipated as heat in the oil brake, supported by a lube oil system that provides cooling and bearing lubrication.

Why choose a Turboexpander-Dyno/Oil Brake?

In some applications, an expander is used to achieve maximum refrigeration in a low-flow process stream. The potential energy recovered from the gas expansion is not enough to justify the investment of an attached generator, or it may not be feasible to attach a compressor. A turboexpander-dyno configuration is the best solution. The energy is absorbed by the dyno wheel rotating in oil and the heat being generated from this activity is dissipated through a cooler.

Benefits of an Expander-Dyno/Oil Brake

More efficient than a JT Valve when there isn’t enough power to justify use of a compressor or generator as the loading device.

LAT is an agile and responsive company with complete control over the design to delivery timeframes for both new equipment and aftermarket projects. From concept to commissioning, L.A. Turbine controls and manages the entire design, engineering, fabrication, assembly and testing process for all projects in its Valencia, CA manufacturing facility. Plus, since all manufacturing and testing is done in-house, customers receive a fully assembled and tested turboexpander unit ready for installation and commissioning upon delivery. Other OEM manufacturers often take possession of outsourced equipment and assemble it for the first time at the customer site. This approach requires additional testing and lengthens the turboexpander commissioning process.
